If a deal is reached this week, will they be able to retroactively uncancel the WC? PLEASE?!

What I've been hearing from almost all sources is that they really don't want to hold the WC this year even if they reach a deal tomorrow. It is supposed to be celebrating everything good about the game. I think everyone is worried that it coudl be a disaster with backlash from the lockout, would be better to defer to next year when hopefully all is forgiven, fresh start, etc.

"If I were to wish for anything, I should not wish for wealth and power, but for the passionate sense of the potential, for the eye which, ever young and ardent, sees the possible. Pleasure disappoints, possibility never. And what wine is so sparkling, what so fragrant, what so intoxicating, as possibility!" - Kierkegaard

Can only be a good sign....why would they be meeting into the wee hours of a Saturday night if they weren't trying to hammer out an actual deal or something very close to it?

One news reporter quoted;

"They were playing call of duty zombies, they got to level 42, couldn't quit. Plus they vowed to finish the whole king size pizza"

Another news reporter;

"They hired some strippers to entertain them while they played video games"

and another;

"they came to an agreement (finally) and they started the nhl season, Daly played as Phoenix, while Fehr played as the all star team in NHL 13. The game quickly erupted in argument about a goal Daly said shouldn't have been allowed, when Fehr won by a goal, Daly enacted a lockout by snapping the disc in half, so and I quote "if it isn't my way, no one gets to play!" then they quickly broke off and took a well deserved break"

Six years from now, Uncle Gary should announce the "postponement" of the Winter Classic in July. This will speed things up and he won't have to worry about his inability to negotiate an agreement the way normal businesses.
That, of course, assumes that Uncle Gary will still have his current job then.

No chance. With people starting to get refunds and the cancellation being official, I'm sure the wheels starting turning for plenty of ticket holders, shareholders, corporate sponsors and all the other stuff that happens behind the scenes the moment the official statement hit the airwaves.
